EARTH HOUR: A LIGHTS-OUT EVENT FOR OUR PLANET

This book introduces Earth Hour, an annual event in which millions of people around the world switch off lights for one hour on a Saturday in March. Children and adults use electricity for many daily activities, and the book invites readers to consider turning off electric lights, using flashlights or lanterns instead. Earth Hour is presented as a global symbol of conserving energy and acting together in appreciation of the planet.
